- VINYLBENZYL-BASED AND STYRENE-BASED ANION EXCHANGE COMPOSITE MEMBRANE HAVING POLYVINYLIDENE FLUORIDE AND METHOD OF PREPARING THEREOF

摘要

Provided is an anion exchange composite membrane comprising: a copolymer including a vinylbenzyl-based repeating unit introduced with a quaternary ammonium group, a styrene-based repeating unit and a divinylbenzene cross-linking repeating unit, and polyvinylidene fluoride. The anion exchange composite membrane comprising: a copolymer including a vinylbenzyl-based repeating unit introduced with a quaternary ammonium group, a styrene-based repeating unit and a divinylbenzene cross-linking repeating unit, and polyvinylidene fluoride not only has low electric resistance, excellent ion exchange abilities, ion conductivity, mechanical properties, chemical properties and processability but can easily adjust the ion exchange abilities and ion conductivity. Also, the anion exchange composite membrane can be easily manufactured at low costs.
